Importance of Photonic QPUs and Quantum Interconnects

Photonic QPUs, such as those developed by Quandela, offer significant advantages due to their inherent modularity. This modular design  enables computing scalability, as additional qubits can be seamlessly integrated into the system. As the carriers of quantum information, photons provide high-speed data transmission with minimal interference, making photonic QPUs highly efficient and reliable for complex quantum computations. Scaling to a large number of qubits will involve the interconnection of multiple independent photonic QPUs, a process that demands additional technological advancements and represents a huge technological challenge in itself.

Full-stack quantum interconnects based on efficient quantum memories are crucial for linking multiple QPUs regardless of the qubit modality. These interconnects enhance the overall computational power by allowing quantum information to be transferred between different processors with high fidelity and low latency. Welinq’s state-of-the-art quantum memories ensure that the integrity of quantum information is maintained during transmission, which is essential for the development of robust and scalable quantum networks.

Implementing a multi-pronged approach

This partnership is in line with Quandela and Welinq’s desire to work together to develop fully-fledged clusters of photonic quantum computers, which would have both hardware and algorithmic advantages over alternative approaches.

This technological partnership is in line with the announcement a few weeks ago of the AQADOC project, the world’s largest initiative dedicated to distributed quantum algorithms, led by Welinq and of which Quandela is a key member. The aim of this project is to explore energy-related use-cases and to develop the next generation of distributed software capabilities, capable of running on several QPUs interconnected by the hardware work to be carried out as part of this strategic partnership.
